1-5 White-spot correction
As a general characteristic unique to CCDs,
white-spots may appear on the screen with age.
In order to reduce this phenomenon, this unit
is equipped with a white-spot correction fea-
ture.
Switch on the camera power supply and wait
for at least 30 minutes.
1. Remove the dome cover.
2. Cover the lens surface using a black sheet
of paper, etc. so that light does not enter
the lens.
3. Press and hold the SPOT CORRECTION
button on the unit for more than 2 seconds.
* White-spot correction will start. Correction
may take several seconds for completion.
Notes
• Maximum correction: less than 16 to 32 spots
• The white-spot correction feature of this unit does not guarantee the correction of all white spots.
Depending on the characteristic of white spots, correction may not be possible.
• When performing white-spot correction, accurate data may not be achieved in case of highly
detailed pixels since correction is made using the information of surrounding pixels.
• The result of white-spot correction is maintained until the next correction is performed.
